APPLICATIONS INFORMATION
EXAMPLES ILLUSTRATING OUTPUT COUPLING
The ADA4430-1 is ideally suited for use as a reconstruction
filter that follows a video DAC or encoder. The application
circuits in Figure 29, Figure 30, and Figure 31 illustrate a
number of ways the ADA4430-1 can be used with a single-
supply current-output DAC on its input and its output ac- and
dc-coupled.

SAG correction allows the use of two small, lower cost
capacitors in place of one large capacitor in applications with
ac-coupled outputs. Circuits with ac-coupled outputs consume
less power than those with dc-coupled outputs.
